SEM images of the hierarchically structured e-sprayed ZTO-Bs on FTO/glass (A and B) and size distribution of ZTO-Bs used in this study (inserted graph – line is the fitted result by Gaussian function), illustration of ZTO-B (C), Diffused reflectance spectra (D), nitrogen sorption isotherms (E) and pore volume distribution of the ZTO based photoelectrodes (green: ZTO-NP, red: ZTO-B). The pore diameter was calculated using desorption branch. For the sake of clearer presentation, the intensity of the isotherms of ZTO-B in (F) were shifted by 100 cm3 g−1 compared to and ZTO-NP.
